“…Hal ini dapat terjadi walaupun mangrove alami memiliki rerata usia lebih tua dibanding campuran karena kontribusi deposisi biomassanya yang lebih rendah. Selain faktor usia, kepadatan karbon sedimen juga dipengaruhi oleh jumlah biomassa yang diproduksi mangrove sebagai salah satu sumber karbon sedimen utama (Wang et al, 2021).…”

“…Diketahui terdapat korelasi negatif yang kuat antara rentang pasang surut dengan kandungan karbon sedimen. Paparan frekuen dari arus pasang surut terhadap sedimen membuat kandungan karbon organik sedimen rentan terbilas dari sedimen dan terlarut dalam kolom air (Wang et al, 2021). Simpanan karbon sedimen pada kedua strata dengan lokasi sebagian besar stasiun yang lebih terpengaruh pasang surut menjadi lebih rendah.…”

Land use change is a huge threat for mangrove ecosystems,which are known for their high carbon sequestration and storage capacity.Vegetation restoration efforts are often undertaken, but fail to restore optimal ecosystem carbon sequestration. The mangrove forest of Perancak Estuary with a history of restoration project was made the subject of this research. The objectives include: (i) estimation of mangrove biomass and sediment carbon stock; (ii) comparison of restored, mixed and natural mangroves’ total carbon stock; (iii) correlational analysis between stand density and diversity indices with ecosystem carbon stock. Nine sampling points were determined within three mangrove categories (mixed, natural, restored). Stand characteristics and diameter at breast height (DBH) were measured to allometrically estimate biomass carbon. Sediment carbon was analyzed with Loss on Ignition (LOI) method. Correlational analysis was done with Pearson’s correlation coefficient. Total ecosystem carbon stock is 4472,93 tonnes ha-1 (biomass C: 4046,31 tonnes ha-1; sediment C: 426,62 tonnes ha-1). Highest carbon stock value was found on restored mangroves due to high contribution of sediment C offsetting its low biomass C. Lowest carbon stock value was found on natural mangroves due to decreased root biomass production and increased decomposition due to change in tidal regimes. There is a strong positive correlation between stand density and biomass carbon. Simpson index of diversity has a stronger (though non significant) correlation with biomass carbon than Shannon-Wiener index.

“…Many scientific studies have revealed that the C accumulated in the soil changes depending on many factors. In these studies, the amount of C in the soils was affected by latitude (Feeney et al, 2021;Wang et al, 2021), litter quantity and decomposition rate (Prietzel and Bachmann, 2012;Lukić et al, 2015), different land use (Li et al, 2015b), tree species (Prietzel and Bachmann, 2012;Sariyildiz et al, 2015), the chemical structure of litter (Sevgi et al, 2011), bulk density (Topa et al, 2021), and climate characteristics (Schrumpf et al, 2011). However, little is known about their carbon storage in different stand development stages of trees.…”

The influence of stand development stages on soil organic carbon (SOC) and total nitrogen (TN) stocks was examined in black pine (Pinus nigra Arnold.), Scots pine (Pinus sylvestris L.), and Kazdağı fir (Abies nordmanniana subsp. equi-trojanı (Aschers. & Sint. ex Boiss) Coode et Cullen), differing in the mean tree diameters in which reproduction stages (RS)=<8 cm, sapling or pole stages (SPS)= 8-19.9 cm, large pole stages (LPS)= 20-35.9 cm, and medium wood stages (MWS)=36-51.9 cm in three tree species located in northwestern Turkey. A total of 216 soil samples were collected and analyzed for pH, organic matter, bulk density, maximum water holding capacity, carbon, and nitrogen concentrations, and the SOC and TN stocks were calculated. SOC and TN stocks varied significantly among the four stand development stage classes. The SOC stock at 0-30 cm increased significantly due to an increase in the diameter of black stands (BPLPS and BPMWS). SOC stocks in all stand development stages peaked in the large pole (44.94 Mg/ha) and declined as the sapling or pole (37.71 Mg/ha) was replaced by medium wood stands (30.17 Mg/ha), and a low point (27.94 Mg/ha) was found in the reproduction stages of stand development for Scots pine. The TN stock at a soil depth of 0-30 cm ranged from 1.66 to 6.46 Mg/ha. The highest TN stock was observed in the SPSPS (6.46 Mg/ha) and FirRS (5.48 Mg/ha), and the lowest was observed in the BPLPS (1.66 Mg/ha) stands. The results illustrate that soil was the main storage of C and N in all different stand development stages of tree species.

“…Accordingly, ongoing/projected warmer conditions have been associated with range expansions into salt marsh habitats at higher latitudes (Cavanaugh et al, 2014). The substantial part of the organic carbon reservoir of mangroves, represented by the AGB (Rovai et al, 2016), is also allocated through physiological responses to thermal conditions (Wang et al, 2021) and, therefore, with significant spatial variability throughout the globe (Giri et al, 2011; Hutchison et al, 2014). In particular, warmer conditions prevailing in subtropical regions are associated with positive effects on the overall productivity of mangroves (Akaji et al, 2019).…”

Aim: Over the past 50 years, anthropogenic activities have led to the disappearance of approximately one-third of the world's mangrove forests and their associated ecosystem services. The synergetic combined effect of projected climate change is likely to further impact mangroves in the years to come, whether by range expansions associated with warming at higher latitudes or large-scale diebacks linked to severe droughts. We provide an estimate of future changes in the extent and aboveground biomass (AGB) of mangrove forests at global scales by considering contrasting Representative Concentration Pathway scenarios (decade 2090-2100 under RCP 2.6 in line with the Paris Agreement expectations, and RCP 8.5 of higher emissions). Location: Global.Methods: Boosted regression trees fitted occurrence and AGB of mangroves against high-resolution biologically meaningful data on air temperature, precipitation, wave energy, slope and distance to river Deltas. Results:On the global scale, models produced for present-day conditions retrieved high accuracy scores and estimated a total area of 12,780,356 ha and overall biomass of 2.29 Pg, in line with previous estimates. Model projections showed poleward shifts along temperate regions, which translated into comparable gains in total area, regardless of the RCP scenario (area change RCP 2.6: 17.29%; RCP 8.5: 15.77%).However, biomass changes were dependent on the emission scenario considered, remaining stable or even increasing under RCP 2.6, or undergoing severe losses across tropical regions under RCP 8.5 (overall biomass change RCP 2.6: 12.97%; RCP 8.5: −11.51%). Such losses were particularly aggravated in countries located in the Tropical Atlantic and Eastern Pacific, and the Western and Eastern Indo-Pacific regions (regions with losses above ~20% in overall biomass). Conclusions:Our global estimates highlight the potential effect of future climate changes on mangrove forests and how broad compliance with the Paris Agreement may counteract severe trajectories of loss. The projections made, also provided at the country level, serve as new baselines to evaluate changes in mangrove carbon sequestration and ecosystem services, strongly supporting policy-making and
